SPECIFICATION forming part of Letters Patent No. 277,962, dated May 22, 1883,

(No model.)

To all whom itmcy concern Be it known that I, FRANCIS A. WALSH, of Chicago, in the county of Cook and State ot' Illinois, haveinvented certain new and useful Improvements in Seaming-Machines; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention relates to make and use the same, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 represents a side elevation ot' my improved machine ready for work, with a part of the cone-pulley broken away. Fig. 2 is a 'front elevation taken on and back of theplane n: m of Fig. 1. Fig.3 is a plan view ot the bracket b,the plate c being removed, and showing an end view of the bed-plate a, and rod c2.

Fig. 4 is a plan view of the bracket g4 and the parts operating in or nearly in the same plane with it, the parts above' being removed. Fig. 5 represents a profile of the circumference of the wheel or cam c. Fig. 6 shows a plan view ot the cam c and gear-wheel dotted underneath it, the worm (Z2 and its shaft, crank, I evers,` and spring to operate the rack h3. Fig. 7 represents a plan view of the rod g and its operating-cam ci and a part ofthe bracket g, which latter is also shown in dotted outlinein a position it is moved into by the rod g. Fig. S shows a central longitudinal sectional elevation of thc gear-wheel d and its shaft and spring in full. Fig. 9 shows a cross-section of the shaft f7, taken in the plane y y', Fig. 4,.

and its rollersflf. Fig. 10 shows the end of the shal'tfG with its roilerj'10 in side elevation. Fig. 1l represents an elevation of a can-body Vprovided with an end ready for putting into farthest position that the shaftf" may turn to from that shown in Fig. 14, and the position of the partly-finished double seam at that positionfof the shal'tf, and also the final position (shown dotted) of the can when the roller fl finally c nnpletes the double seam. Fig. 16 shows the final completion of the double seam by the roller f1". Fig.vl7 represents a plan view, and Fig. 1S a side elevation, ot' the attach ment, to the seaming-machine, used either for beading cans singly, or for both scanning and beading them singly, or for beading a series ofc-ans with ends already seamed to onel end of thecan-body, or for both beading and seaming them at the same time. Fig. 19 shows the construction of the plate o8 as formed when used in connection with the mandrels 7.13 when it is desired to make the end without or but a slight countersink after the double seam is iinished. the plates c and 08, mandrel 7a3, and

'can k* being shown in a vertical central section, and the rollers f8 ff having hold ot' the can and its cover, ready to turn down the parts so held into a double seam, and the opposite side showing' the seam finished.

Like letters of reference indicate like parts. My invention consists in the construction of the various improved parts of a double-seaming machine as herein shown, so that it will now automatically clamp the can-body and one ot' its ends together between two adjustable revolving chucks, with which the can revolves on its axis, and while so turning one end is united to the body with a double seam by means of automatically-operating mechanism, which consists of a single roller that :first turns down the burr or flange of the cover against the body of the can, and next ot' a pair of rollers attached to areeiprocally and partially revolving shaft, which then turn down the can-body and wall of the countersunk part of the cover over and so near against the can-body that Ithe seam may then finally be pressed down against the can-body Aby the sameroller first mentioned'above; and said reciprocating shaft is so connected with other mechanism that it may be arrested in its action on the partly-finished double seam and caused to leave it standing at right angles to the body ofthe can, orV at any other desired angle; and

automatically released from the chucks, .ready to drop or be taken out ofthe machine, all as hereinafter more fully described.

In the drawings, A represents the standard of the machine, to the frontot' which is attached a bed-plate, a, upon which slides a bracket, b, carrying a disk, c, which spins freely` on a spindle, c. Said bracket bis firmly attached to a rod, c2, at any desired elevation, by means of a set-screw, c3. The rod c2 cxtends upward through the bracket or bearing c", in which it works freely, and yoke c5, in which it is held and minutely adjusted b v the The other end ofthe yokec5 has a long` hub which slides freely upon the shaft d, and at or near the center of said yoke is a roller, ci, the axis of which is parallel with a central vertical plane through the yoke. Said roller runs upon the upper side of la wheel, c, the upper side ot' which is formed into an irregular cani, the developed profile of which is shown in Fig. 5. rlhe wheel e is tirmly attached to the shaft d, and immediately below, on the same shaft, is attached a worm-wheel, e', gearing into the worm r1.2,txedon the shaft d3. Said shaft d is carried in a bracket, d. To the outer end of the shaft di* are attached the cone-pulleys d4, from which the machine receives its motion, and to the other end of said shaft d3 is attached a bevel-pinion, d5, meshing into the wheel d, which, with its shaft and spring, is shown more fully in an enlarged sectional view in Fig. S. Said gears di d5 and the worm d2 and worm-wheel e are so constructed that while the cam e is making one revolution the wheel d is making somewhat more than three revolutions, for the upper chuck or plate, c, is attached to its shaft, and this determines the number of revolutions the can-body makes for the different operations while making the double seam. The shaft o9 slides freely up and down in the bearingsin the arms dT d. The long hub of the wheel d is turned down, so as to form a shoulder resting on the `arm d, while the part below the shoulder plays in the bearing in said arm, and is provided on its inside with a groove'in which plays a feather, dg, attached to the shaft e9. The upper part of the hub of said wheel is chainbered or bored out to make room for a spring, el, to play freely. Said spring rests upon a collar resting upon a shoulder of the shaft o9, and the upper end of said spring bears against the arm dl.

On the shaft d, below the bearing d', are attached cams c2 e3, and to the end of said shaft a crank, c". The cam c2 is provided with spurs or wipers ffX upon its circumference, which work against the spur or toef, attached to the upper sideof the rod f2. Said rod works on the under side of the cam c2, and is provided with a slot, f", through which the shaft d passes, and which serves to guide it in its operation.

To the outer end of the rod f2 is attached a post',f4, of which the lower end is provided with a collar and a set-screw, f5. Said collar slides freely on the shaftf, and is fixed on it at any desired place by the set-screw f5. The shaft f6 passes through and its center coincides with that ot' the outerjournal of f7, and carries on its inner end a roller, f 10. Said roller is moved in and out to and from the can, first, to turn down the flange u of the cover, as shown in Fig. 12; second, to complete'the partly-formed double seam, as shown in Fig. 16, after the rollersfaj'9 have first turned it into the form or position shown in Fig. 15. Vhen the seam is completed as far as can be done bythe rollers ,f8 f9 the roller f8 has to be passed out from its position Linder the seam, which may be done either by moving the shaft f7 or the rollerj8 on the shaft down below the seam, or else by lifting the can up into the position shown dotted in Fig. 15, and which in this case is accomplished by the cam e. The spurs ffX draw the roller againstthecan, and the springj'3 throws it back as soon as released from said spurs.

The rod g surrounds the`-lower end ot' the cam e3, which is provided with a single wiper or spur, y2, which works against the toe or projection g on the rod g for the purpose of throwing1 the bracket g4, turning on the pin g5, around into the dotted position shown, and thus withdraw the rollersfgf9 from the can. When the seam is brought at right angles to the canbody, as shown in Fig. 14, and when the spurs g g2 have passed each other, the spring gG Awill throw. said bracket into its proper position again.

To the under side of the rod surrounding the cam e3 is attached a plate', c4, (shown dotted in Fig. 7,) provided with a slot, gi, through which the shaft d passes, and which serves to guide the rod g.

To the crank-pin c5 is attached a rod, h, provided at its outer end with a slot, t, in which plays a pin or stud, t', attached to the rod h.` The rod h works on a stud, t2, at or near its center, and around the stud 2 is wound a spring, t3, with a tension tending to throw the rod h inward, as indicated by the arrow. The outer end of the bar h is also provided with a slot in which plays a stud, t, fixed to the rack h3. Said rack passes on the under side cf' and meshes with the pinion h4, adjustably attached to the shaftfi.

The mechanism to bead the cans is constructed substantially as follows: Directly in front of the scathing-machine is fixed a post, upon which revolves in a horizontal plane a disk or spider, r, provided with equidistant holes 702,'into which are placed mandrels k3, of a size to fit into the cans to be beaded. A can, 764, is shown over such a mandrel, (shown in dotted outline within,) and the beading-roller 765 just relieved from it. Said mandrels extend to the end of the can to support the head for the `purpose of turning over all or nearly all of the wall of the countersink ofthe coverinto the douole seam, and therebyl make the can fiat-bottomed.

When it is not desirable to work the countersink out of the ends, asjust described, but

provided. The journal of said mandrel is provided with a conical socket in its lower end and at its center, into which fit-s the corresponding conical point ofthe pin c', upon which the mandrel is carried and turnsduringthe operation of beading and seaming. Mandrels 7c3 7.10 are both made tonearly tit theinterior of the can, room enough being left so that the can may be lifted from the mandrel after being beaded. The mandrel It is intended, as shown,

' for\a much smaller can than k3, and is shown in its proper place in opening 7a2 of spider. Of`

course mandrels of only one kind and size can orare to'be used at the same time. The sides of the can will yield sufficiently to the pressure ofthe roller kf to form a bead. Thelower end of the can is supported o n the,` flange 7c", w.ith which all the mandrels must be provided. The plate c should be made as thin asrpossible and its edge beveled down sharp, as shown in Fig. 19, so that the rollers f8 f may take hold and begin to form the double scam at or nearly at the base ot the wall of the counter sink, so that when the double sea-in is com pleted the countersink will practically be out ofthe end of the can, or so as to leave but a slight mark. The beading roller l' turns freelyin a lever, k6, pivoted to the horn kT of the bracket l), so as to work in a horizontal plane, and is caused to work against the cans 'by the wedge m, attached to the bed-plate a by 'the set-screw m2, as the bracket b rises.

To the side ofthepost A is attached aspring, Z, provided with a rounded projection, 769, to lit into the notches k, and of such a length-that when the spark9 is in a notch k it will hold the conical socket of the mandrel directlyover the point'of the pin c'.

To the under side ot' the disk k is attached a ratchet-wheel, Z, into which works-a ratchet, Z2', on a lever, Z3, pivoted at Z4, and'soproportioned and adjusted to the lower end ot' the rod c2 that every time the rod c2 descends it operates the lever Z3 and causes the disk k to r i i l' turn around, pulling the spring Zout ot' the notch 708, and catching in the next succeeding one, and thus stop the next mandrel atits proper place. The rod e2, yoke c5, and bracket `b have sufficient weight to turn the spider la',

which is made light and so as toturn easily; but should the pressure on the lever Z3 thus obtained not be great enough, the bracket b may be made heavier or a weight added toit, or a spring attached to itfroin the tloor or base of the machine.

0 represents a counting apparatus, from which projects a rod or lever, o', whichoperates'its mechanism, and which may be oper: ated'by the spur o2 on the shaft cZ, and which turns around once; or it may be operated by the-yoke c5, which rises once for every can seamed. v

The arrows indicate the direction-ot' motion ofthe different parts. i

The operation ofthe foregoingdescribed machinery is as follows, to wit: A chuck'or plate, o8, of a size to t into the conutersunk end ot' the cans to be operated upon, is first attached to the lower end of the spindle ci. Next the disk c is adjusted to the proper point to suit l the height of said cans, and the rollerfwis set so as to work properlyion the rim u ot' covers ot' given diameter. When all is ready a cover, p, is' placed upon the can q, which is then placed centrally uponthe plate .or table c and thetrcadlej pressed down. By the arrangement of rods and levers shown this will raise the roller c7 out ot' thenotch h5, and -thus relieve the spring i, wound around the post 2, and cause the shaft d to turn, vand the worm d?, which was heretofore playingin the blank a, to engage with the worm -wheel, which then turns the shaft until the roller c7 again drops into the notch -h5.. When the calnwheel e is thus'made to turn, the roller c7 first runs over the level s3, then up the inclined plane s, and thereby litts the yoke c5, and with it the attached rod c2 and bracket I), and thus drives the head p ot' the can against the plate c, and thereby clamps the can tightly between the plates c and c", whieh'now, by` frictional contact with plate c, will revolve, the shaft e9 rising against the pressure ot' the spring cl". The can is automatically adjusted and begins to revolve as the roller cT runs up the inclined plane s. By the time that roller c7 arrives on the level s one ot' the spurs or wipers of the cam c2 has engaged with the spurf, attached to therod f2, and drawn the roller f1" against the rim of the can-cover and caused it to turn down said rim against the body of the can, as shown in Fig. 12,' the spurf being made long enough so thatthe can may revolve once while the rollerfl operates7 after which it is released and pushed back out of the way by the spring f3. At any time after the roller]v10 has turned down a sufficient part ofthe rim of the cover,

as shown in Fig. 12, the rollers f8 ff' may begin to operate. The can and cover are lifted up by the adjusted bracket b between the rollers ff f, as shown iu Fig. 13, so that said rollers may operate at the proper point to form the double seam. The rollers flfJ are operated by the crank ci and the intermediate parts, h h" h3.v As the action of the spring yi3 is to throw the rack h3 outward, itwill cause the shaft f7 to turn so as to throw the roller f5 down snugly upon the plate e8, and hold it there during the time thoat part ot' the rim of the cover isv being turned down. \/Vhile this is being done the pin t" plays in the slot i. After the cranlrpin has passed sufticiently beyond the other side ot' the center of the shaft Z so that the end of the slot will play against the -pin t" it begins to push the rack h3 in the op- IOO IOS

lifts up onto the plane s2 of the cam e and lifts with it the plate c, and thus forces the partlyformed double seam to pass up and out from between the rollers f8 ff into the position shown dotted in Fig. 15, (this part has been more fully and completelyexplained in aformer application referring more particularly t0 this part,) and simultaneously the spur or wiperf comes in contact with the toe f and again `pushes the roller fw in contact with the can, (said roller being made high or long enough,) and thus finishes the double seam by turning it down against the body of the can, as shown in Fig. 1G, and by the time the wheel e has -thus made one complete revolution the roller cT has arrived at and again dropped into the notch h5 and stopped the revolution of the shaft d, and this also drops the table o, so that the can may be taken out from between the plates e8 o. When it is desired to work continuously and more rapidly, the lever j? may be set by the nutj4 so that the rod c2 will not permit the roller cT to drop to the bottom of the notch h5. The spring t3 will therefore cause the worm-wheel e to pass the gap o' and instantly re-engage the worin-wheel with the worm d2, while the roller o7 runs ou the short plane s, thereby producing a continuous and uninterrupted motion of said machinery.

Instead of having the notch i' in the wormwheel e' for the purpose of stopping the machinery at each completion of a can, a Mason friction-clutch may be placed into the conepulley d4 and operated through a rod and lever by the falling yoke c5 of rod c2.

When it is desired to form what may be called a partial double seam,7 such as is shown formed on the can in Fig. 14, the necessary mechanism to be added to that already described for forming the complete double seam consists of a cam, e3, on shaft d, formed as shown in Fig. 7, which operates a rod, g, one end of which is formed into a ring surrounding said cani c3, and has on one side ot' its inner circumference aspur or toe, g,'against which the wiper g2 strikes and causes the rod g to pull the bracket g1 around into the position shown in dotted outline on the bolt or center g5, the spring c5 resisting and throwing it back into its first position as soon as the spur g2 and toe or spur g have passed each other. I

To the under side ofthe rod surrounding the cam c3 is attached a plate, e4, (shown dotted in Fig. 7,) which is provided with a slot, gl, through it to pass the shaft d for the purpose of guiding the rod g in its longitudinal mo'- tion. lhe plate et rests on the hub of the crank c5. The spur g2 and toe g are so placed as to pull the bracket gL into the dotted position at the instant that the partial double seam is formed, as already stated, and shown in Fig. 14, and thus throw the rollers f8 f5 out and away from the seam, while all the alreadydescribed parts and said rollers f8 f 9 go through their full motion, so as to finally release the can from its chucks.

It is also evident in this case that the mechanism used to throw the rollers f8 fg from the Y e. Many other forms of lifting device might be shown to lift the can at fixed and positive intervals to exact previously-determined points. The mandrels k3 7c" turn freely in their bearings in the plate k', and are raised by the center o when thecans are either seamed or beaded. The roller f1 may be arranged in any other manner desired, or even attached to a lever and worked by hand. The bolt c may be lowered in its socket, the plate c removed, and the spindle of a mandrel, to, heldin the bracket b, so that it may turn on the bolt or spindle c, and cans placed on said mandrel may then be beaded without the use of the spider and its attached mechanism. The rod c2 may have an arm projecting from it. to which the roller c7 is attached, as the rod 02 is clamped by the bolt c3, so that it cannot turn around in its bearings and operate quite as well as with the yoke; or the roller o7 may be attached directly to the rod c2, in either ease adjustably attached; but the way shown is preferable because it diminishes friction.
